POLISHING MOP OR THE LIKE.

Application filed. January 31, 1921. Serial No. 441,498.

To all w/wm z't may concern:

Be it known that we, HARRY ROBERT Onion, subject of the King of GreatBrit ain, and resident of The Old House, Hamble, Hants, England, andFnavn OXLEY HELLIWELL and WILLIAM PLUMBRIDGE, botn subjects of the Kingof Great Britain, and residents of 10 Shorncliife Road, Folkstone, Kent,England, have invented certain new and, useful Improvements Relating toPol ishing Mops or the like, of which the following is a specification.

This invention relates to mops or the like of the manually operated kindin which a disc or equivalent element is applied with one face to thesurface to be treated as dis tinct from cleaning or polishing devices ofthe rolling cylinder type. The invention relates particularly to mops ofthe kind used for polishing floors and consisting of a disc mounted on ahandle and provided peripherally with lengths of coarse yarn, fibre,fabric, or similar material suitable for polishing. The usual method ofusing such a mop is to make the material and disc travel to and fro on'the surface to be cleaned or polished by impartiu a reciprocating motionto the handle. The chief object of the present invention is to increasethe effectiveness of the reciprocating motion and incidentally reducethe amount of energy or pressure required to obtain the desired efi'ect.

According to the present invention the disc portion of the mop ismounted rotatably upon the handle in such a way that the pressuredirected upon the rear face of the disc portion while manipulating themop causes said disc portion to rotate as it travels. For the sake ofmechanical balance and symmetry of design, two discs are convenientlymounted upon the two limbs of the branched or forked end of the handle.In order to obtain the desired r0- tation of the discs all that isnecessary is mounting so that the disc does not press awkwardness inmanipulation.

upon the surface equally at all points on its periphery. I

he invention will now be described more fully with reference to theaccompanying drawings which represent by way of example three simpleembodiments. I

Figure 1 is a plan view of a polishing mop with a single disc.

Figure 2 is a sectional elevation of a mop with a pair of symmetricallyplaced discs.

Figure 3 is a plan view and Figure 4 is a sectional elevation of thepreferred form of our invention.

Referring first to Figure 1, it will be seen that the mop comprises thehandle 1, he handle socket 2, the peripherally dished disc 3, and thefabric, fibres or yarn a peripherally attached to the disc by an elasticband or in any other convenient'manner. The disc 4 is rotatably mountedupon one end of an arm 5 to the other end of which the socket 2 isattached. The socket is forked to embrace a roller 6 which is rotatablymounted on the arm 5. It will be understood that as the handle is movedto and fro and pressed towards the floor or other surface to cause thedisc and cleaning material to travel over it the pressure will cause theroller 6 to press eccentrically upon the disc and thereby cause thelatter to rotate as it travels thus easing the to and fro movement andproducing a far more effective cleaning and polishing effect than wouldresult from a plain reciprocating motion.

It will be apparent that the construction shown in Figure 1 presents thedisadvantage of lack ofmechanical balance tending to set up undesirablestrain and a certain These defects are readily overcome by mounting adisc on each end of the arm and attaching the socket to the armsymmetrically between the discs as shown in Figure 2. This figure shewsdiscs 3 and 3 mounted with their planes slightly tilted towards eachother, whereby the reaction from the floor being greatest at the pointsof nearest approach to the surface being cleaned causes an excess ofpressure to be applied eccentrically and aconsequent rotative motion toaccompany the reciprocating or travelling motion of the discs.

Figures 3 and 4 illustrate a twin-disc mop wherein the eccentricallyapplied pressure is derived from rollers 6 and 6 on the cross arm 5instead of by inclining the planes of the discs. It will be obvious fromthis figure that as the handle is reciprocated the discs will not onlytravel to and fro on the surface being cleaned or polished but will alsorotate. It may be noted that the connection of the handle socket withthe cross piece is such that the handle can be rocked about the axis ofthe cross-piece.

l/Ve believe that the principle of utilizing the manually appliedpressure on the handle of a mop of the kind described to cause arotation of the cleaning or polishing disclike members as they travel toand fro is broadly new, and We Wish it to be understood than anyanalogous application of this principle is Within the scope of ourinvention. For example instead of fabric rags, yarn or the likepolishing material we might employ bristles in Which case the devicewould be more in the nature of a brush though operat ing on preciselythe same principle.

What We claim is 1. A polishing mop or the like comprising a handle, anangularly extending arm thereon, a disc rotatably mounted on said armand adapted to be reciprocated on one face thereof mopping material onsaid disc, and means for applying the pressure exerted in reciprocatingsaid disc eccentrically to said disc to rotate the same as it travels.

2. A polishing mop or the like comprising a handle, an angularlyextending arm there on, a disc rotatably mounted on said arm and adaptedto be reciprocated on one face thereof, mopping material on said discand a roller for applying the pressure exerted in re-- ciprocating saiddisc eccentrically to said disc to rotate the same as it travels.

3. A polishing mop or the like comprising a handle, a cross piecethereon, a disc rotatably mounted on said cross piece, a roller on saidcross piece bearing eccentricallyon one face of said disc, and cleaningor polishing material interposed between the other face of said disc andthe surface to be cleaned or polished.

4. A polishing mop or the like comprising a handle, a cross piecethereon, a disc rotatably mounted. on each end of said cross piece,mopping material on said discs, and means for applying the pressureexerted in reciprocating said discs eccentrically to said discs torotate the same as they travel.

5. A polishing mop or the like comprising a handle, a cross piecethereon, a disc rotatably mounted on each end of said cross piecemopping material on said discs, and rollers on said cross piece bearingeccentrically on the rear faces of said discs to cause them to rotate asthey travel With their front faces on the surface to be cleaned.

6 A polishing mop or the like comprising a handle, a cross piecethereon, a peripherally grooved disc rotatably mounted on saidcross-piece, a roller on said cross piece hearing eccentrically'upon therear face of said disc, polishing material for interposition between thefront face of said disc and the surface to be polished, and meansdetachably securing said material to the periphery of said disc.

7. A polishing mop or the like comprising a handle, a cross piecethereon, a peripherally grooved disc rotat-ably mounted on each end ofsaid cross piece, rollers on said crosspiece bearing eccentrically onthe rear faces of said discs, cleaning-material on said discs forinterposition between the front faces of said discs and the surface tobe cleaned, and means detachably securing the cleaning material to theperipheries of said discs.
